Reports 'connected' but not works

sofos

OpenVPN Connect (Android) connects to the server, shows correct IP (192.168.252.2) assigned by the server, but ping could not reach server's IP (192.168.252.1). What additional information is required?

Update:

$ ip route show

10.196.191.80/30 dev rmnet0 proto kernel scope link src 10.196.191.81

213.87.1.1 via 10.196.191.82 dev rmnet0

192.168.253.0/24 is a LAN behind the server.

Does anyone know how to get OpenVPN Connect (Android) log (which is printed on its log screen) as text? Or maybe a place where it is saved?

After

trans=TO_CONNECTED

log is continuously (every 10 sec.) being append with

time_signature -- TUN write error: write_some: invalid argument

What does it mean?

Just a guess, since you haven't posted any configs, but if you compression enabled in your client's config file, try 'comp-lzo yes' instead of just 'comp-lzo'. I had a similar log file and symptoms and found this fixed it.

I had this, when I tried to force no compression by specifying:

comp-lzo no

Removing that line helped.
